I am using postal as my SMTP for my email marketing campaign. I am currently using Putty open-source terminal emulator and winSCP basic file manager and file synchronization to put my project together.
I am unable to open my IP address I have set up for postal. I have asked my current VPS provider to diagnose what the issue may be. This is what I was told.
The issue is the following:
2020/10/13 21:53:15 [error] 24654#24654: *7 connect() failed (111: Connection refused) while connecting to upstream, client: 178.238.239.246, server: postal.yourdomain.com, request: "GET / HTTP/1.1", upstream: "", host: "postal.cheerorganics.co"
This basically means that you have set Nginx as a reverse proxy to some service that listens on port 5000, however when seeing what services listen on what port (for instance with the netstat -punta command), there is no service that listens on that port.
PLEASE HELP!!! FYI I am a newbie to this world.
Reset to default
